After a material is chosen for your rotary kiln refractory, you must decide the desired heat loss. When efficiency is of concern, or very high temperatures are involved, often it is desirable to use multiple layers of refractory: a “working” layer, and an insulating layer. …
Refractory is what protects the shell of a direct rotary kiln from the heat within, so as you can imagine, choosing a quality refractory that is right for your material is extremely important in the design of a rotary kiln. Choosing a refractory that will …
Holding the appropriate temperature within a rotary kiln is what allows the desired chemical reaction to occur. Sustaining that temperature, however, can be difficult if the right seal is not chosen. Almost all rotary kilns run at a negative pressure, meaning gas doesn’t leak out, …
Rotary kilns are integral to modern industrial processing, providing a controlled means of initiating chemical reactions and phase changes. As they are highly flexible and can be used to process hundreds of different materials, optimizing the performance of a rotary kiln around the process and …
Rotary kilns are used in a variety of thermal processing applications, and depending on the material being processed and the process objectives, internal components are often employed to improve efficiency. One such component is the bed disturber, widely employed in indirect kilns. While not always …
Rotary kilns are a highly engineered thermal processing device, capable of carrying out a wide variety of objectives, from catalyst production to metal recovery. While much of the design of a rotary kiln is engineered around the unique characteristics of the material to be processed …
Once we have our preliminary rotary kiln size, we can start to think about the details of the rotary kiln internals. In the case of a direct fired rotary kiln, in which the hot stream of gas flows directly through the interior of the rotary …
When designing a thermal processing operation, confusion often results on whether a direct-fired or indirect-fired kiln is the better option. And while there can be some overlap in applications, in general, each type of kiln is better suited for different processes. Below is a brief …
Rotary kilns are widely used throughout many industries to carry out various chemical reactions and physical changes in bulk solids. As all materials respond differently, rotary kilns must be designed around the exact project specifications and material characteristics at hand in order to reach an …
Rotary kilns are widely used throughout a variety of industries to carry out chemical reactions and phase changes in materials. A highly engineered device, rotary kilns must be designed around the specific requirements of the material and project goals at hand. Rotary kiln design takes …
